What materials are needed for fermentation cooling in fermentation tanks

What materials are needed for fermentation cooling in fermentation tanks? The fermentation tank fermentation cooling consumes less energy by directly cooling the fermentation tank and wine liquid, and the cooling medium has a high heat transfer coefficient under forced circulation. In traditional fermentation and wine storage, most of the cold energy is consumed in cooling the factory building, air, operators and machines (such as pumps, motors), fermentation tank supports, etc. According to calculations and measurements, fermentation tank fermentation can save 40% to 55% of cooling consumption compared with traditional fermentation.

1. Fermentation tank cleaning and disinfection Traditional fermentation tanks and wine storage tanks basically rely on manual cleaning and disinfection, and it is impossible to achieve automated programming. Fermentation tank fermentation can rely on CIP automatic program cleaning and disinfection, and process hygiene is easier to ensure.

2. Of course, fermentation tank fermentation also has weaknesses. Because the tank is relatively high and the yeast sedimentation layer is thick, the number of generations of yeast mud used is generally lower than that of traditional yeast (only 5 to 6 generations can be used); when storing wine, clarification is more difficult (especially when using non-coagulant yeast), and filtration must be strengthened ; If single-brew fermentation is used, the temperature of the tank wall and the center of the tank must be consistent, which usually takes more than 5 to 7 days. Short-term wine storage cannot guarantee consistent temperatures.
